• isolates
  • A total of 47 Campylobacter isolates (28 C. jejuni and 19 C. coli ) isolated from various retail meat samples (beef, beef livers, pork, chicken, turkey, chicken livers, and chicken gizzards) were subjected to pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). (mdpi.com)
  • PFGE was able to group the 47 Campylobacter isolates into two major clusters (one for C. jejuni and one for C. coli ) but failed to differentiate the isolates according to their source. (mdpi.com)
  • Twelve of the screened Campylobacter isolates (8 C. jejuni and 4 C. coli ) did not show any defined STs. (mdpi.com)
  • All the defined STs of C. coli isolates belonged to ST-828 complex. (mdpi.com)
  • It is worthy to mention that, while the majority of Campylobacter isolates in this study showed STs that are commonly associated with human infections along with other sources, most of the STs from chicken livers were solely reported in human cases. (mdpi.com)
  • In conclusion, retail meat Campylobacter isolates tested in this study particularly those from chicken livers showed relatedness to STs commonly associated with humans. (mdpi.com)
  • Molecular typing, particularly MLST, proved to be a helpful tool in suggesting this relatedness to Campylobacter human isolates. (mdpi.com)
  • A total of 552 Campylobacter isolates (281 Campylobacter jejuni and 271 Campylobacter coli ) isolated from retail meat samples were subjected to arsenic resistance profiling using the following arsenic compounds: arsanilic acid (4-2,048 μg/mL), roxarsone (4-2048 μg/mL), arsenate (16-8,192 μg/mL) and arsenite (4-2,048 μg/mL). (mdpi.com)
  • A total of 223 of these isolates (114 Campylobacter jejuni and 109 Campylobacter coli ) were further analyzed for the presence of five arsenic resistance genes ( arsP , arsR , arsC , acr3 , and arsB ) by PCR. (mdpi.com)
  • Most of the 552 Campylobacter isolates were able to survive at higher concentrations of arsanilic acid (512-2,048 μg/mL), roxarsone (512-2,048 μg/mL), and arsenate (128-1,024 μg/mL), but at lower concentrations for arsenite (4-16 μg/mL). (mdpi.com)
  • The presence of arsC and acr3 did not significantly increase arsenic resistance with the exception of conferring resistance to higher concentrations of arsenate to some Campylobacter isolates. (mdpi.com)
  • To our knowledge, this is the first study to determine arsenic resistance and the prevalence of arsenic resistance genes in such a large number of Campylobacter isolates. (mdpi.com)
  • Eighty-seven C. jejuni and 15 C. coli isolates were analyzed by flaA HRM and also partial flaA sequencing. (qld.gov.au)
  • All 53 E. coli O157:H7 isolates were resistant to Talmicosin and Erythromycin, two antimicrobials used in food animal medicine. (k-state.edu)
  • strains
  • In collaboration with The Genome Analysis Centre (TGAC) and the University of East Anglia, partners with IFR on the Norwich Research Park, and scientists at the University of Swansea, University of Liverpool and Public Health England, the researchers will carry out next generation genome sequencing of 500 genomes from C. coli strains. (themeatsite.com)
  • The aim of the present study was to compare PFGE and MLST in typing strains of C. jejuni and C. coli that were isolated from different Oklahoma retail meat sources. (mdpi.com)
  • The early 21st century produced several reports of walkers and cyclists alike developing strains of E.coli and campylobacter which, if left untreated, can be fatal. (wikipedia.org)
  • infections
  • C. coli infections are commonly sporadic and show seasonal trends, with most cases occurring in late summer/early fall in developed countries, although the reason for this pattern is not fully understood Footnote 5 . (canada.ca)
  • Cryptosporidium
  • parasites: Giardia lamblia (with high frequency of infestation in the population, but not always with clinical manifestations), Balantidium coli, Blastocystis homnis, Cryptosporidium (diarrhea in people with immunosuppression), Entamoeba histolytica (produces the amebian dysentery, common in tropical areas). (wikipedia.org)
  • molecular
  • UK - The Food Standards Agency has given a Strategic Research grant to a consortium led by Dr Arnoud van Vliet of the Institute of Food Research, to develop new tools to understand Campylobacter coli at the molecular and genetic level. (themeatsite.com)
  • prevalence
  • C. coli is of worldwide prevalence, and is common in both developed and developing countries with most outbreaks related to food or water-borne causes Footnote 3 , Footnote 4 . (canada.ca)
  • The prevalence of campylobacter on chicken carcasses is very high and cross contamination can easily occur during food preparation. (canada.ca)
  • study
  • The knowledge obtained from this two-year study could be used to develop diagnostic tools to help confirm diagnose and track sources of C. coli contamination - a tool we do not currently have. (themeatsite.com)
  • known
  • Much less is known about the biology of C. coli - including where it resides in the environment and how it infects us. (themeatsite.com)
